The study was conducted to determine the variability and association between yield and yield components of Castor accessions. Data such as, (Plant Height, Leaf Area, Node to Primary Panicle, Branches per plant, Panicle per plant, Days to 50% Maturity, Capsule per plant, 100-seed weight and seed yield per plant) were evaluated at two locations (Lafia and Makurdi) using Randomized Complete Block Design. Among the fourteen traits evaluated, there were large GxE interaction for 5 traits observed viz; Capsule/Plant, days to 50% Maturity, 100-seed weight and seed yield/plant implying significant environmental influence in the manifestation of these traits. The result of correlation analysis revealed that Panicle/plant, Capsule/plant, Panicle length and Branches had negative and significant correlation with seed yield. Wide disparity in the estimate of genetic variation was observed for all the traits. Phenotypic variations in many of the traits were largely non-genetic and broad sense heritability estimate were relatively high for most of the traits except branches per plant. Among the treatments, accession 9 gave the best yield (492.1 and 759.7) kg/ha at both locations, followed by accessions 2 and 5 yielding (418.2-452) kg/ha at Makurdi and accession 7 yielding 494.32 kg/ha at Lafia. This suggested that accession 2, 5, 7 and 9 could be used in crosses to isolate high yield lines in breeding.
